Voici une rare vidéo de la paisible vie à Hiroshima avant la bombe nucléaire. What About the Bombing of Nagasaki? At 3:47 A.M. on August 9, 1945, a B-29 Superfortress took off from the American airbase on the island of Tinian, in the North Pacific Ocean. Operation Centerboard II, the mission to drop the second atomic bomb on a Japanese city, had begun. Already things were not going as smoothly as they had three days earlier, in the run over Hiroshima. That attack had been textbook—“operationally routine,” as a classified Army history later put it. The Enola Gay had reached its target and returned home without complication; an announcement sent out under President Harry Truman’s name had trumpeted its success.
Bockscar had been stripped of most of its armor and weaponry to accommodate its five-ton atomic payload, known as the Fat Man. The crew had been expressly ordered to pick out their target visually, rather than by radar, since the explosive reach of the bomb, although astonishing, was still limited enough that to be off by a mile or two might result in the majority of its power being wasted. Control Room of the Synchrophasotron, c.1975. “The Synchrophasotron was a synchrotron-based particle accelerator for protons at the Joint Institute for Nuclear Research in Dubna that was operational from 1957 - 2003.” - Wikipedia. Atomic Bomb Footage: Tinian (1945) - Part 1. Hiroshima Atomic Bomb (1945) When We Tested Nuclear Bombs - In Focus. Since the time of Trinity -- the first nuclear explosion in 1945 -- nearly 2,000 nuclear tests have been performed.
Most of these occurred during the 1960s and 1970s. When the technology was new, tests were frequent and often spectacular, and they led to the development of newer, more deadly weapons. Since the 1990s, there have been efforts to limit the testing of nuclear weapons, including a U.S. moratorium and a U.N. comprehensive test ban treaty. As a result, testing has slowed -- though not halted -- and there are looming questions about who will take over for those experienced engineers who are now near retirement? Gathered here are images from the first 30 years of nuclear testing.

World Heritage: Hiroshima Peace Memorial (Genbaku Dome) (360° Panorama) This series of 360° panoramic images shows Hiroshima as you’ve never seen it before—from the inside of the A-Bomb Dome (normally closed to the public) to the August 6 memorial ceremony, the Peace Memorial Museum, and the lantern floating ceremony held to commemorate those who died in the world’s first nuclear attack.
At 8:15 in the morning on August 6, 1945, “Little Boy,” the world’s first atomic bomb, was dropped on the center of Hiroshima. Around 90% of the 76,000 buildings in the old center of the city were destroyed. The civilian and military population of the city at the time was around 350,000; it is estimated that 140,000 died by the end of the year. Many more continued to suffer from the effects of radiation for many years. The Genbaku Dome as it originally looked. Today, almost 70 years later, Hiroshima has been reborn. A memorial ceremony is held on August 6 every year.
